Error I can not fix in my wii console

I bought a wii console, it is not able to connect to the internet, it is not able to find any access point. The console is wii white, old version, it was able to read some cheep game discs I bought from stores, I tried to burn wii and gamecube games on dvd discs, the wii failed to read them, I used the usb loader and the back up loader and neogamma, all of them failed. I read a subject to update it without using the internet, it was updated to wii 4.3u, I thought it is the better region, but failed to read discs, even the discs that the wii was able to read them became unable to being read.

I don't know what to do!

My console made crazy!
